iPhone 18 Pro Max audio output randomly switches when using USB-C to AUX cable

On my Iphone 18 Pro Max when using a USBC to AUX cable after listening for maybe 10 minutes through it my IPhone randomly switches to outputting audio through the phone for half a second then back to the cable. This pauses the music and when I press play it does it a second time usually. Only had problems with my new phone, my 16 worked just fine with jt.
